Can you reduce this to the simplest combination of scripts?
(That don't use sessions).

did you checked if php_stream_read() was returning the right filesize
value? that was the first bug.

Note: Calling sleep(5) before dumping the PDF solves the problem, so I
think the bug is related to a memory management/multithreading
problem...

Environment: Windows
WebServer: Microweb (CD-WebServer)
PHP-Version: Latest CVS and 4.2.4-dev
PHP is installed as CGI

In a frameset-environment, PHP hangs while outputting large PDF-Files.
The Frameset consists of three Frames. Every Frame is PHP-generated.
One functions as "PDF-Passthrough".

All works fine, if the Passthrough-File is smaller than approx. 100k.
Files >100k make the system hang.

Calling the passthrough-script directly (w/o frameset) causes no
problems.

There is no difference between using readfile, fpassthru, or fread.
